ポレータ２１となる。 This laminated type evaporator 21 has a thin plate 22 that is fitted with the middle skin of a confectionery to form a liquid passage pipe 23 as shown in FIG. Liquid pipe 23,2
A corrugated fin 24 is interposed between the three. That is, the thin plate 22 has deep bulges formed at both ends, and an intermediate portion 25 connecting the deep bulges at both ends has a flat cross-section and a substantially U-shape with a shallow recess. When the pair of thin plates 22 are brought together in the middle, liquid reservoirs 26 and 27 are formed at both ends, and a liquid passage pipe 23 in which both the liquid reservoirs 26 and 27 are communicated through a flat liquid pipe 28 made of an intermediate part 25. is configured. The liquid reservoir portion 26 or 27 is connected to each other,
A large number of them are connected in a communicating state through the through holes 29 or 30,
The stacked evaporator 21 is obtained by inserting an inlet conduit 31 for introducing refrigerant into the lower liquid reservoir 27 group and connecting an outlet conduit 33 for discharging the refrigerant to the upper liquid reservoir 26 group.

The refrigerant flows from the inlet side conduit 31 through the lower liquid reservoir 27 into the liquid passage pipe 23 group, and while the refrigerant flows through the liquid passage pipe 23 group, corrugated heat transfer fins 24 (hereinafter referred to as corrugated fins) are introduced. The heat is taken away from the air flowing through the space (referred to as ``refrigerant''), the air is evaporated, the air is cooled by the heat of evaporation, and the evaporated refrigerant is transferred to the upper liquid reservoir 2.

ある。(Problem to be solved by the invention) However, in the case of the condensed water scattering prevention structure of this stacked evaporator, a wire mesh is installed on the leeward side, which increases the number of parts and assembly man-hours, leading to an increase in manufacturing costs. Furthermore, there are disadvantages such as a decrease in air volume due to an increase in passing air resistance and an increase in total weight.

とする積層型エバポレータである。 The purpose of the present invention is to eliminate the drawbacks of the above-mentioned prior art and provide a laminated evaporator that is inexpensive and lightweight in structure and can prevent the scattering of condensed water. In order to achieve this object, the present invention has a pair of thin plates formed in such a manner that a plurality of grooves which are inclined upwardly toward the downstream side in the direction of wind flow are interspersed with each other. As a result, the bulging portions at both ends form part of the upper liquid reservoir and the lower liquid reservoir, and the intermediate portion is formed into a liquid passage pipe that communicates between the two liquid reservoirs, and a large number of these liquid passage pipes are arranged in a row. In a stacked evaporator in which heat transfer fins are interposed between the outer surfaces of adjacent liquid passage pipes, the inner end surface of the groove is located on the downstream side of the groove formed in one of the thin plates in the direction of air flow. The end of the plate formed on the other thin plate is in surface contact with the downstream end in the wind flow direction, and the end of the plate formed on the other thin plate on the upstream side in the wind flow direction is formed on the one thin plate. The laminated evaporator is characterized in that it is configured so as to make surface contact with the upstream end of the next groove in the wind flow direction.
前記溝部は、好ましくは、各薄板の略全面にわ
たり複列複行に整列して形成することが望まし
い。 The grooves are preferably formed in double rows and double rows over substantially the entire surface of each thin plate.

ける金綱の設置も廃止が可能となる。(Function) In this way, the condensed water is collected in the groove, allowed to fall along the groove, and quickly discharged from the bottom of the evaporator itself, thereby preventing the condensed water from scattering to the leeward side of the evaporator. This also makes it possible to abolish the installation of wire ropes in conventional cases.
両薄板に空気の流れ方向に向つて上り傾斜した
溝部をそれぞれ形成したため、エバポレータ自体
の保水力も向上し、これによつても凝縮水の風下
側飛散が少なくなる。 Since grooves that slope upward in the direction of air flow are formed in both thin plates, the water retention capacity of the evaporator itself is improved, and this also reduces the scattering of condensed water on the lee side.
溝部の内部端面の接合も一点接合ではなく二点
接合になるため、通液管の剛性も向上することに
なる。 Since the inner end surfaces of the grooves are joined at two points instead of at one point, the rigidity of the liquid passage tube is also improved.

とが望ましい。 This laminated evaporator 40 is configured such that the groove portion 34 formed in the thin plate P slopes upward in the downstream direction in the air flow direction shown in FIG. In the illustrated example, 23 grooves 34 are formed in four rows in the air flow direction and in the vertical direction. However, the number of rows and columns of the grooves 34 does not matter as long as the water retention and drainage from the evaporator itself are sufficiently achieved, but preferably, the grooves 34 are arranged in double rows and double rows over almost the entire surface of each thin plate. It is desirable that it be formed.

る。 In particular, in this embodiment, as is clear from FIGS. 3, 4 and 6, the inner end surfaces 34 of each groove 34,
a, 35a are grooves 34 formed in one thin plate P.
The downstream end in the wind flow direction (hereinafter sometimes referred to as the rear end 42 for simplicity) is connected to the other thin plate P.
The end of the groove formed on the other thin plate P on the upstream side in the wind flow direction (hereinafter sometimes referred to as the starting end 43 for simplicity) is in surface contact with the rear end 42 of the groove 35 formed on the other thin plate P. It is configured to make surface contact with the starting end 43 of the next groove formed in one of the thin plates P.

下側に凝縮水が飛散することはない。 Grooves 34 and 35 formed in both thin plates P in this way
If both are inclined upward in the direction of air flow, no matter which liquid passage pipe 41 the condensed water accumulates on the surface of, the condensed water will flow down along the grooves 34 and 35. That is, this condensed water does not flow toward the leeward side, but rather flows toward the windward side, and the condensed water does not scatter toward the leeward side of the stacked evaporator 40.

a indicates the rear end 42 of one groove 34, the rear end 42 of the other groove 35, and the starting end 43 of one groove 34.
Since the starting end 43 of the groove 35 and the other groove 35 are surface-joined, the number of joints is doubled compared to the conventional one-point joining method, and the rigidity and strength of the liquid passage pipe 41 are more than doubled. It turns out.

The corrugated fins 4a protrude by a predetermined length (4 mm to 6 mm), and the condensed water flowing along the corrugated fins 24 or the thin plate P is caused to flow along the corrugated fins 24 to prevent it from scattering to the leeward side of the laminated evaporator.

い。 In the embodiment described above, four rows of grooves are formed in the thin plate P, but the number of rows and columns of the grooves 34 and 35 or the pitch between the grooves 34 and 35 may be changed as appropriate depending on the capacity of the evaporator. I can do it. For example, as shown in FIG. 7, the grooves may be formed so as to be coarse, such as 12 grooves in four rows.Alternatively, although not shown, the grooves 34 may be formed in a staggered manner with respect to the air flow direction. You can. In this case,
The length of one of the grooves may be made longer than the other.

なる。(Effects of the invention) As described above, according to the invention, condensed water is collected in the groove, allowed to fall along the groove, and promptly discharged from the bottom of the evaporator itself. Scattering can be prevented, and in some cases, the installation of wire mesh in conventional examples can be eliminated.
